High Dose Atorvastatin for Preventing Periprocedural Ischemic Brain Damage During Carotid Artery Stenting (PICAS)

April 8, 2020 updated by: Jun Lu, Beijing Hospital

Efficacy of Two Different Doses of Atorvastatin for Prevention of Periprocedural Ischemic Brain Damage in Chinese Patients Undergoing Carotid Artery Stenting (CAS)

The purpose is to test whether a short-term, high-dose atorvastatin treatment (80mg once a daily (QD) from 3 days before to 3 days after CAS, then 20 mg QD until 30 days after CAS) is superior to conventional-dose atorvastatin treatment (20 mg QD from 3 days before to 30 days after CAS), in terms of efficacy for prevention of periprocedural ischemic brain damage in Chinese patients undergoing CAS.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Chinese patients with carotid stenosis scheduled for selective CAS will be randomized into two groups. The High-dose Atorvastatin group will receive Atorvastatin 80 mg QD from 3 days before to 3 days after CAS, then 20 mg QD until 30 days after CAS, while the Conventional-dose Atorvastatin group will receive Atorvastatin 20 mg QD from 3 days before to 30 days after CAS. All patients will receive cerebral diffusion-weighted (DW)-MRI within 7 days before CAS. Then, they will also receive repeated DW-MRI within 5 days after CAS. Efficacy for prevention of periprocedural ischemic brain damage of the two different Atorvastatin treatments will be compared, in terms of periprocedural incidence of transient ischemic attack (TIA)/ ischaemic stroke or new ischemic lesions on cerebral DW-MRI.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
